Non-polar amino acids are those which have no overall charge. Of the twenty amno acids there are five charged and fifteen uncharged, these are:
(A) Alanine
(C) Cystein
(F) Phenylalanine
(G Glycine
(I) Isoleucine
(L) Leucine
(M) Methionine
(N) Asparagine
(P) Proline
(Q) Glutamine
(S) Serine
(T) Threonine
(V) Valine
(W) Tryptophan
(Y) Tyrosine
The overall charge of an amino acid is determined by the R group attached to the alpha carbon atom. Those with a carboxyl R group will have an overall negative charge, whereas those with a amide group have an positive charge. [1].
